User Management API Tutorial 📘

Welcome to the User Management API tutorial! This guide will walk you through the essentials of designing and implementing a RESTful API for managing user data. Whether you're building a web app, mobile service, or backend system, this knowledge is crucial.

Core Endpoints 🔑

A typical user management API includes the following endpoints:

POST /users – Create a new user
GET /users/{id} – Retrieve user details
PUT /users/{id} – Update user information
DELETE /users/{id} – Delete a user
GET /users – List all users

🌟 Tip: Always include authentication tokens in request headers for secure access.

Security Best Practices ⚠️

Use HTTPS to encrypt data transmission
Implement JWT (JSON Web Token) for stateless authentication
Validate input data to prevent injection attacks
Set proper rate limits to avoid abuse
Store passwords using bcrypt or argon2

Example Requests 📡

Here are sample requests for common operations:

Create User

POST /users
Content-Type: application/json
Authorization: Bearer <token>

{
  "username": "john_doe",
  "email": "john@example.com",
  "password": "secure_password"
}

Update User

PUT /users/123
Content-Type: application/json
Authorization: Bearer <token>

{
  "email": "john_new@example.com"
}
